Norden Crown Metals Corp. ( " Norden Crown " or the " Company ") (TSXV: NOCR) (OTC: NOCRF) ( Frankfurt : 03E) is pleased to provide an exploration update for its Burfjord Copper-Gold Project ("Burfjord") in northern Norway which is 100% owned but subject to an option (as described further, below) and its 100% owned Gumsberg Project ("Gumsberg"), located in the Bergslagan province in southern Sweden .
Norden Crown , in partnership with Boliden Mineral AB ("Boliden"), recently completed a 9 hole, 2,208.7 metre exploration drilling program at Burfjord, which was designed to test selected geological, geochemical and geophysical targets, with geochemical results expected in the coming weeks (Figure 1). In addition to diamond drilling, Norden Crown completed 21.5 line-kilometres of ground–based time domain electromagnetic geophysics ("TEM") over high priority targets at Burfjord with the objective of identifying conductive copper sulphide mineralization for the purpose of drill testing (Figure 1).
Norden Crown is currently planning a soil sampling campaign and a high-resolution magnetic survey at the Fredriksson Gruva prospect at Gumsberg. Results from this work will be combined with ongoing lithological and structural mapping to produce a 3-dimensional interpretation of the distribution of silver-zinc-lead mineralization and will form the basis of a follow up drilling program at Gumsberg.
EXPLORATION AT BURFJORD COPPER GOLD PROJECT, NORWAY
Norden Crown , together with partner Boliden, recently completed a Phase I diamond drill program and a 21.5 line-kilometre ground–based TEM survey at Burfjord. Phase II of a previously announced UAV magnetic survey 1 is planned for Q4 2021. Previous drilling by Norden Crown 2 at Burfjord returned compelling results including an intercept of 32 metres averaging 0.56% copper and 0.26 g/t gold (including 3.46 metres of 4.31% copper and 2.22 g/t gold) at shallow depths below a cluster of historic mine workings 3,4 . Historical drilling at Burfjord (Cedarsgruvan) was reported to have returned 7.0 metres averaging 3.6% copper 5 .
Burfjord Diamond Drilling
A total of 9 holes (2,208.7 metres) have been drilled at Burfjord to test high priority Iron Oxide Copper Gold ("IOCG") targets located within the highly copper-gold anomalous Burfjord Anticline (Figure 1). Diamond drilling was focused on lithological, structural, geochemical and geophysical targets with the objective of determining the upside copper-gold potential of the Burfjord Project. Drilling was completed to an average depth of 245 metres and geochemical results are expected in the coming weeks.
Burfjord Time Domain Electromagnetic Geophysics
Norden Crown engaged GRM Geophysics ( Finland ) to conduct approximately 21.5 line–kilometres of TEM geophysics at Burfjord. The survey includes one loop and expands coverage of the TEM data collected in 2020 1 , which identified a high-priority conductor measuring 1,900 metres between copper targets at Gamlegruvan and A-Gruva (Figure 1). TEM geophysics at Burfjord is used to identify conductive materials including inter-connected sulphide minerals such as chalcopyrite. Conductive anomalies identified using TEM geophysics are used to increase confidence in previously identified lithological, structural and geochemical targets (Figure 1). Furthermore, resistivity and conductivity data obtained from the TEM survey will enhance Norden Crown's geological interpretations and will be used to track copper and gold associated sulphide mineralization at depth and to increase confidence in the planned exploration drilling targets. Results of this recent TEM survey are expected in the coming weeks.
Burfjord Joint Venture Terms
Norden Crown entered into an option agreement (the "Agreement") with Boliden in respect to Burfjord 6 . In order to earn a 51% interest in the Project, Boliden must fund 100% of the exploration programs by spending US$6 Million within four years of the date of the Agreement.
Overview of the Burfjord Project
Burfjord, located in the Kåfjord Copper Belt near Alta, Norway , is highly prospective for IOCG and sediment hosted copper mineral deposits. Copper-gold veins at Burfjord that were historically mined (pre 20th century) at reported cut-off grades of 3-5% Cu are surrounded by envelopes of stockwork veins or disseminations of copper mineralization extending tens to hundreds of metres laterally into the host rocks.
Norden Crown and Boliden believe this mineralization has economic potential and represents an attractive bulk tonnage exploration target. Burfjord is comprised of six exploration licenses totaling 5,500 hectares in the Kåfjord Copper Belt near Alta in Norway . During the nineteenth century, copper mineralization was mined from over 30 historic mines and prospects developed along the flanks of a prominent 4 x 6-kilometre fold (anticline) consisting of interbedded sedimentary and volcanic rocks. Many of the rocks in the anticline are intensely hydrothermally altered and contain sulphide mineralization.
EXPLORATION AT GUMSBERG SILVER-ZINC-LEAD, SOUTHERN SWEDEN
Ongoing 2021 exploration work at Gumsberg is focused on expanding the footprint of Broken Hill-Type ("BHT") mineralization intercepted at the Fredriksson Gruva historical mine workings in March 2021 7 . A Phase I geological mapping and sampling program has been completed and Norden Crown is planning a high resolution magnetic geophysical survey which will be used to trace strongly magnetic mineralization (magnetite associated) in the subsurface. Precious metal enriched based metal mineralization at Fredriksson Gruva is spatially associated with a broader horizon of magnetic iron and manganese-rich chemical sedimentary rocks. This thick magnetic sequence is geologically and geophysically distinctive and can be modeled in three dimensions using detailed magnetic data. Regional magnetic geophysical data sourced from the Geological Survey of Sweden suggests that the prospective magnetic anomaly (and coincident magnetite-bearing iron formation) extends over 21 kilometres across the Gumsberg West Licence (southwest of Fredriksson Gruva), greatly enhancing the exploration potential for additional BHT discoveries (see Figure 2).
An extensive, tightly spaced high resolution ground magnetic survey is planned at Fredriksson Gruva and is expected to commence in Q4 2021. Results from this survey will be integrated with geological mapping and soil sampling data to generate a 3-dimensional interpretation of silver-zinc-lead mineralization at Fredriksson Gruva and will form the basis of a follow up diamond drilling program to test the continuity, grade and distribution of BHT mineralization.
